🥗 Ingredients

The Sunchokes

  • 1.5 pounds Jerusalem Artichokes (Sunchokes) (scrubbed clean, skin left on)
  • 2 tablespoons Kosher Salt (for boiling water)
  • 3 tablespoons Extra Virgin Olive Oil (high quality)
  • 2 tablespoons Unsalted Butter (melted)
  • 1/2 teaspoon Black Pepper (freshly cracked)

Aromatic Gremolata

  • 1/4 cup Fresh Flat-Leaf Parsley (finely chopped)
  • 1 piece Lemon (zested and juiced)
  • 2 cloves Garlic (minced into a paste)
  • 1/4 teaspoon Red Chili Flakes (optional for heat)

Finishing Touches

  • 1 teaspoon Maldon Flaky Sea Salt (for crunch)
  • 2 tablespoons Parmigiano-Reggiano (freshly grated)
  • 2 sprigs Fresh Thyme (leaves stripped)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 425°F (220°C) and place a large rimmed baking sheet inside to get hot while you prepare the vegetables.

  2. 2

    Thoroughly scrub the sunchokes with a vegetable brush to remove any grit from the crevices. There is no need to peel them, as the skin becomes beautifully crisp.

  3. 3

    Place the cleaned sunchokes in a large pot and cover with cold water by at least 2 inches. Add the 2 tablespoons of kosher salt.

  4. 4

    Bring the water to a boil, then reduce heat to a simmer. Cook for 12-18 minutes, or until the sunchokes are fork-tender but not falling apart.

  5. 5

    Drain the sunchokes in a colander and let them steam dry for 5 minutes. This step is crucial for achieving maximum crispiness in the oven.

  6. 6

    In a small bowl, whisk together the melted butter and olive oil. Toss the warm sunchokes in this mixture until evenly coated.

  7. 7

    Carefully remove the hot baking sheet from the oven. Arrange the sunchokes on the sheet, giving them plenty of space.

  8. 8

    Using the bottom of a heavy glass or a potato masher, gently press down on each sunchoke until it is about 1/2 inch thick and the edges are slightly jagged.

  9. 9

    Season with freshly cracked black pepper and thyme leaves. Transfer back to the oven and roast for 20-25 minutes.

  10. 10

    While the sunchokes roast, prepare the gremolata by mixing the parsley, lemon zest, minced garlic, and chili flakes in a small bowl.

  11. 11

    Halfway through roasting, use a spatula to carefully flip the sunchokes to ensure both sides become golden brown.

  12. 12

    Once the sunchokes are deeply golden and the edges look lacy and crisp, remove them from the oven.

  13. 13

    Immediately sprinkle with the grated Parmigiano-Reggiano and the lemon juice while they are still sizzling.

  14. 14

    Garnish with the fresh gremolata and a generous sprinkle of Maldon flaky sea salt. Serve hot immediately.

💡 Chef's Tips

Choose sunchokes that are similar in size to ensure they cook at the same rate. If you find sunchokes difficult to digest, boiling them with a splash of vinegar can help break down the inulin. Don't crowd the baking sheet; if the sunchokes are too close together, they will steam instead of crisping up. Use a high-smoke point olive oil or a blend of oil and butter for the best flavor and texture. For a vegan version, simply omit the butter and cheese, using a high-quality truffle oil as a finishing touch instead.

🍽️ Serving Suggestions

Pair these with a roasted rack of lamb or a pan-seared ribeye steak. Serve alongside a crisp, acidic white wine like a Sancerre or Sauvignon Blanc to cut through the richness. They make an excellent accompaniment to a creamy mushroom risotto. Try them as a sophisticated appetizer dipped in a lemon-tarragon aioli. Add them to a warm grain bowl with farro, kale, and a tahini dressing.
